Background: Social Capital on health has been studied widely, to date there is no valid and reliable questionnaire that measure it in Chronic Kidney Disease (CKD). Objective: To develop, validate and assess the reliability of Social Capital related to CKD questionnaire for Mexican adolescents. Methods: An instrumental study was employed to validate a questionnaire that assesses the cognitive and structural domains of Social Capital related to CKD. The questionnaire was generated by operationalization of the constructs and validated by assessing the content, face validity, criteria and construct validity. Reliability was assessed through the Cronbach´s alpha. Results: The content validity of the questionnaire was confirmed through Kendall’s W of 0.925 (p = 0.01) and its face validity was evaluated by four focus groups. A principal component analysis on a sample of 281 adolescents indicated that 72.78% of the variance was explained by the cognitive domain and 83.20% by the structural domain. A confirmatory analysis returned a chi-squared value of 142.99 (p = 0.05), a CFI of 0.97, a TLI of 0.96, a RMSEA of 0.040 and a SRMR of 0.07 for the cognitive domain. Similarly, a chi-squared of 408.296 (p < 0.001), a CFI of 0.98, a TLI of 0.97, a RMSEA 0.03 and a SRMR of 0.06 were returned for the structural domain. The validity of the criteria was assessed through a Pearson’s correlation for both the cognitive and structural domains. There was a mild-to-strongly significant correlation (p ≤ 0.001) among items and dimensions within each domain, with correlation coefficients ranging from 0.23 to 0.83. As a determinant of the reliability of the questionnaire, the Cronbach’s alpha was 0.84 and 0.94 for the cognitive and structural domain, respectively. Conclusions: A valid and reliable questionnaire has been developed to measure the influence of Social Capital on health in relation to CKD among Mexican adolescents. ©The authors ©Public Library of Science (PLoS) ©PLOS One.

Integrated kidney care requires synergistic linkage between preventative care for people at risk for chronic kidney disease and health services providing care for people with kidney disease, ensuring holistic and coordinated care as people transition between acute and chronic kidney disease and the 3 modalities of kidney failure management: conservative kidney management, transplantation, and dialysis. People with kidney failure have many supportive care needs throughout their illness, regardless of treatment modality. Kidney supportive care is therefore a vital part of this integrated framework, but is nonexistent, poorly developed, and/or poorly integrated with kidney care in many settings, especially in low- and middle-income countries. To address this, the International Society of Nephrology has (i) coordinated the development of consensus definitions of conservative kidney management and kidney supportive care to promote international understanding and awareness of these active treatments; and (ii) identified key considerations for the development and expansion of conservative kidney management and kidney supportive care programs, especially in low resource settings, where access to kidney replacement therapy is restricted or not available. This article presents the definitions for conservative kidney management and kidney supportive care; describes their core components with some illustrative examples to highlight key points; and describes some of the additional considerations for delivering conservative kidney management and kidney supportive care in low resource settings. ©Elsevier

Background and aims: Rapid changes in haemoglobin (Hb) following treatment with erythropoiesis-stimulating agents (ESAs) in patients with anaemia of chronic kidney disease (CKD) have been suggested to be associated with adverse outcomes [1–3]. This exploratory post-hoc analysis was performed to investigate the association between absolute Hb values or Hb changes over a 4-week period and the occurrence of first adjudicated major adverse cardiovascular event (MACE) in CKD patients not on dialysis who were treated with either daprodustat or darbepoetin. Method: ASCEND-ND was an event driven, cardiovascular outcomes trial conducted in over 30 countries that randomized 3872 CKD patients not on dialysis with baseline Hb of 8–10 g/dL if not on a prior ESA, or 8–11 g/dL if receiving an ESA, to receive either oral, once-daily daprodustat (1937 patients) or subcutaneous darbepoetin (1935 patients). Available doses were daprodustat 1–24 mg once-daily and darbepoetin 20–400 µg total 4-weekly dose. The study was recently reported to have met the co-primary endpoints of non-inferiority for first occurrence of adjudicated MACE and mean Hb change from baseline to weeks 28 through 52 [4]. MACE was a composite of death from any cause, non-fatal myocardial infarction or non-fatal stroke, and events were adjudicated by an independent clinical events committee blinded to treatment assignment. In this exploratory post-hoc analysis, we examined the associations of post-randomization absolute Hb values and Hb changes categorized into quintiles (see Table 1) with first adjudicated MACE. Each patient's time in the study, prior to a first MACE or end of follow-up, was divided into distinct 4-week intervals, with each interval associated with a particular post-randomization Hb value and rate of change. Separately for each treatment group, these 4-week periods were grouped according to quintiles of Hb values, and MACE rates were calculated for each quintile. This analysis was repeated using quintiles derived from Hb rate of decrease and increase. MACEs that occurred prior to Week 4, the first scheduled post-randomization Hb collection, were not included in the analysis. Copyright © Oxford University Press

The current report presents comparisons of pain reduction and heart rate response using supplemental virtual reality (VR) pain distraction between 22 indigenous and 22 urban patients during ambulatory surgery. Material and methods. Forty-four (44) patients participated under full informed consent. Half (n = 22) were indigenous peoples and half (n = 22) were urban patients (those residing in Mexico City). For the urban group, a surgeon performed ambulatory surgeries with local anesthesia to remove lesions in soft tissues, such as lipomas, cysts located in the head, neck, back, shoulders, arms, limbs, and abdomen. For the indigenous group, operating rooms, intravenous line, analgesics, and sedatives were not used. Materials included laptop-linked virtual reality, PlayStation, Smartphones and Google Cardboard googles alongside virtual environments such as Enchanted Forest, The Sea, Lake Valley, Jurassic Dinosaur and Coast Space VR. Results. Pain scale indicated 2.92 before, 1.67 during and 0.67 after for indigenous participants, and 5.8 before, 3.32 during and 1.48 after for urban participants. Heart rate responses in indigenous were 80.42(before), 78.5 (during) and 72.42 (after) and urban responses were 74.07 (before), 68.53 (during) and 73.1(after). Discussion. Indigenous patients presented more pain reduction during ambulatory surgery without intravenous lines, analgesics or sedatives and required recovery time or hospitalization. Supplemental VR during medical and surgical procedures is discussed in light of cultural, economic and psychological variables associated with medical care in Mexico. ©2019, Interactive Media Institute.

Late referral of patients with chronic kidney disease (CKD) to specialized care by the nephrologist is associated with worse patient outcomes while on dialysis. To determine the prevalence, risk factors, and consequences of late nephrology referral at a Mexican tertiary care hospital. Retrospective chart review of all adult patients who began chronic hemodialysis between 2002 and 2006 at the National Institute of Cardiology "Ignacio Chavez" (NICICh), Mexico City. Timing of referral to Nephrology Department was classified as early, late or very late if the time elapsed between referral and initiation of dialysis was < 1 month, between 1-6 months or > or = 6 months, respectively. Socio-demographic, clinical, laboratory and echocardiographic characteristics were compared according to timing of referral. Eighty four out of 150 patients were included in the analysis. Of these, 56% were referred < 1 month, and an additional 15% between 1-6 months prior to the initiation of chronic hemodialysis. In univariate analysis, being referred by a relative or friend was associated with a higher risk (p = 0.04), and being employed with a lower risk of late referral (p = 0.05). Late referred patients were more likely to require emergency dialysis and hospitalization, and of not having a permanent vascular access for their first dialysis. They also had a higher prevalence of severe anemia (hematocrit < 28%) and of residual kidney function (estimated glomerular filtration rate < 5 mL/min/1.73 m2), as well as increased left ventricular mass. Late nephrology referral is highly prevalent in our population and is associated with markers of suboptimal predialysis care at the onset of chronic dialysis.

Nephrology in Mexico started in 1955 with the opening of the nephrology department at Mexico’s National Heart Institute, where the first nephrology training program began in 1958. Pediatric nephrology care was first offered at Mexico’s Federico Gomez Children’s Hospital in 1953, among the first pediatric nephrology programs in the world. Kidney transplantation began in 1963 at the IMSS General Hospital. The Sociedad Mexicana de Nefrologia, the first Mexican nephrology society, was established in 1967, followed by the publication of Nefrologia Mexicana, its official journal, in 1980. Chronic kidney disease has emerged as a public health problem in Mexico. However, the fragmentation of the health system has resulted in unequal access to renal replacement therapy. Seguro Popular, a public health-care insurance for the poor, does not cover renal replacement therapy. As a consequence, many uninsured patients refuse dialysis, eventually abandon their treatment, or lose their kidney grafts because sustaining dialysis or immunosuppression becomes unaffordable. The lack of a national dialysis registry results in a vacuum of information on the burden of treated end-stage renal disease and its outcomes. In addition to the high burden of traditional risk factors (i.e., diabetes mellitus), a number of “hotspots” of chronic kidney disease of unknown origin have been recently described in the country. Despite the increased burden of chronic kidney disease, strategies to prevent chronic kidney disease have not been part of the nation’s noncommunicable disease health policies. Chronic kidney disease screening is not part of the National Health Surveys. Peritoneal dialysis continues to be the dialysis modality of choice, although a significant shift to hemodialysis has been observed over the last two decades. The number of nephrologists (9.1 per million population) is insufficient to match the demand imposed by the burden of chronic kidney disease. In conclusion, after 65 years of the beginning of nephrology in Mexico, kidney disease care remains unjust, unequal, and below the quality of international standards. The current infrastructure and resources are insufficient to satisfy the demand of renal care in our society. Therefore, it is important to consider it as a public health priority and to implement a comprehensive program for the prevention and control of this illness. The establishment of a national public policy for the prevention and treatment of chronic kidney disease is urgently needed. © Springer Nature

In nondialysis CKD (ND-CKD), anemia is a multifactorial and complex condition in which several dysfunctions dynamically contribute to a reduction in circulating hemoglobin (Hb) levels in red blood cells. Anemia is common in CKD and represents an important and modifiable risk factor for poor clinical outcomes. Importantly, symptoms related to anemia, including reduced physical functioning and fatigue, have been identified as high priorities by patients with CKD. The current management of anemia in ND-CKD (i.e., parameters to initiate treatment, Hb and iron indexes targets, choice of therapies, and effect of treatment on clinical and patient-reported outcomes) remains controversial. In this review article, we explore the epidemiology of anemia in ND-CKD and revise current recommendations and controversies in its management. Exploring data from real-world clinical practices, particularly from the Chronic Kidney Disease Outcomes and Practice Patterns Study (CKDopps), we highlight the current challenges to translating current recommendations to clinical practice, providing patients' perspectives of anemia and how it affects their quality of life. Finally, we summarize recent advances in the field of anemia that may change the way this condition will be managed in the future. Copyright © 2020 by the American Society of Nephrology.

Anemia of chronic kidney disease and end-stage renal disease: Are there unique issues in disadvantaged populations?
(2009-03)
Several sources of data indicate that there are racial and ethnic disparities in the management of anemia of chronic kidney disease and end-stage renal disease. In this article, I present evidence documenting these disparities and discuss possible factors that may explain the suboptimal anemia management. I also provide recommendations to improve anemia management in disadvantaged populations.

Systemic complications of chronic kidney disease
(2015)
;
Pereira, Brian J. G.
The kidney plays a critical role in the maintenance of homeostasis. As kidney function diminishes, excretory, regulatory, and endocrine function is lost, and complications develop in essentially every organ system. Kidney failure is the last stage in the continuum of progressive CKD. Management of the complications associated with CKD mainly includes dietary counseling, adequate control of volume and blood pressure, and use of phosphate binders, calcitriol (Calcijex, Rocaltrol), and erythropoietin. Many of these complications can be prevented or attenuated with optimal CKD care, which involves early detection of progressive kidney disease, interventions to retard its progression, prevention of uremic complications, attenuation of comorbid conditions, adequate preparation for kidney replacement therapy, and timely initiation of dialysis (figure 2). Closer attention to CKD care is likely to be the key to improved outcomes among patients with kidney failure.
